Edwardie Fileupload Better -

Reading large files into FileReader can crash mobile browsers. Edwardie uses streaming (ReadableStream API) with backpressure support, keeping memory usage under 10MB even for 10GB files.

Sometimes you don't need form data; you just need to push a raw binary file (e.g., uploading an image directly to S3 or a blob storage endpoint).

Edwardie handles this elegantly without requiring you to manually set boundaries.

The Code:

PUT https://storage.example.com/bucket/image.jpg
Authorization: Bearer <token>
Content-Type: image/jpeg
< ./images/image.jpg

The single most impactful change you can make is switching from buffering to streaming.

The "Bad" Way (Default):

// The file sits entirely in memory.
HttpPostedFile file = Request.Files["upload"];
byte[] buffer = new byte[file.ContentLength]; // Dangerous for large files
file.InputStream.Read(buffer, 0, file.ContentLength);

The "Better" Way (Streaming): We will bypass the default model binding and access the raw HTTP Input Stream.

public async Task<bool> StreamEdwardieUpload(HttpContext context)
var multipartMemoryThreshold = 81920; // 80kb buffer
    var provider = new MultipartFormDataStreamProvider("C:\\TempUploads");
// This streams to disk, not RAM
await Request.Content.ReadAsMultipartAsync(provider, multipartMemoryThreshold);
foreach (var file in provider.FileData)
// Process the file directly from the temp location
    using (var fileStream = File.OpenRead(file.LocalFileName))
// Stream to cloud storage (Azure/S3) without holding RAM
        await UploadToCloudAsync(fileStream);
return true;

Why this is better: Your server can now theoretically handle 10GB files without breaking a sweat. Edwardie is no longer the weak link.

If you don't have time to rewrite the Edwardie logic, offload the "better" part to a dedicated service. This is the fastest path to improvement.

Options:

Direct-to-Cloud Pattern:

// Client gets a temporary URL
public string GetSasTokenForUpload()
var sas = blobContainer.GetSharedAccessSignature(new BlobSasBuilder()
ExpiresOn = DateTimeOffset.UtcNow.AddMinutes(30),
        Protocol = SasProtocol.Https
    );
    return blob.Uri + sas;
// User uploads directly to Microsoft's servers.
// Edwardie only handles the metadata.

This reduces server load by 100% and makes uploads 10x faster. edwardie fileupload better

Create a new view to display the file upload interface:

<!-- file-upload.blade.php -->
<div class="dropzone" id="file-upload">
    <div class="dz-message">
        <h2>Drop files here or click to upload</h2>
    </div>
</div>
<script>
    $(document).ready(function() 
        var dropzone = new Dropzone('#file-upload', 
            url: ' route('file.upload') ',
            method: 'post',
            paramName: 'file',
            maxFiles: 1,
            maxFilesize: 2,
            acceptedFiles: '.pdf, .docx, .doc',
            dictDefaultMessage: 'Drop files here or click to upload',
        );
    );
</script>

import  EdwardieUploader  from 'edwardie-fileupload';
function App() 
const handleSuccess = (file, response) => 
console.log($file.name uploaded successfully, response);
;
const handleError = (error, file) => 
console.error(Failed to upload $file.name:, error);
;
return (
<EdwardieUploader
endpoint="https://api.yourservice.com/upload"
allowedTypes=['image/jpeg', 'image/png', 'application/pdf']
maxFileSize=10 * 1024 * 1024 // 10 MB
multiple=true
chunkSize=2 * 1024 * 1024 // 2 MB chunks
onSuccess=handleSuccess
onError=handleError
showPreview=true
/>
);
